title: [Imaging of actinic porokeratosis by optical coherence tomography (OCT)].
abstract: Disseminated superficial actinic porokeratosis (DSAP) is a rare, genetically heterogeneous skin disorder. We report a case of a 73-year-old female patient who was diagnosed with DSAP by optical coherence tomography (OCT) and histology. During the last 4 years prior to diagnosis, she had developed numerous (pre)malignant lesions of the skin of the lower legs including actinic keratoses, squamous cell carcinomas and Bowen's disease. DSAP lesions and actinic keratoses were resistant to topical treatment with imiquimod and retinoids, but improved with photodynamic therapy (PDT).
